Abstract
We have studied optical and electric properties of conducting polymers with heteroatoms such as Si and Sn in main chains. Heteroatoms, which are the same group with carbon atom, in each monomer unit of polymer main chains, are expected to possess unique characteristics and functionalities. The strong photoluminescence (PL) with high quantum efficiency and electroluminescence have been clarified, and these polymers have been exhibited the excellent optical properties and spectral narrowing. We also demonstrated pulsed, photopumped multimode laser emission from cylindrical microcavities formed by the polymer thin films deposited around optical fibers and the polymer microdisks. The bright blue laser emission could be observed.
